[0032] Figure 1 It is a schematic diagram of modules of a mobile device 100 according to an exemplary embodiment. Figure 2 yes Figure 1 Another schematic diagram of modules of the mobile device 100 is shown. Figure 3 FIG. 1 is a schematic diagram showing an arrangement of a camera device 10 and a distance measuring device 20 at a viewing angle according to an exemplary embodiment. Figure 4 It is a schematic diagram showing an imaging surface S1 of a camera device 10, a ranging surface S2 of a ranging device 20, and a ranging reference viewing surface S3 according to an exemplary embodiment. Figure 5 The diagram is a schematic diagram showing an imaging surface of another camera device, a ranging surface of a ranging device, and a ranging reference field of view according to an exemplary embodiment. Figure 6 It is a schematic diagram showing another perspective arrangement of a camera device 10 and a distance measuring device 20 according to an exemplary embodiment. The mobile device 100 mentioned here can be a mobile phone, camera, tablet computer, wearable terminal device, etc. with a camera function.

[0033] Please refer to Figure 1 , and when necessary, combine Figures 2 to 6As shown, the mobile device 100 includes a camera device 10, a distance measuring device 20 and a processor 30. The processor 30 is connected to the distance measuring device 20 for communication, and can send a distance measuring instruction to the distance measuring device 20, and can receive the distance measuring data sent by the distance measuring device 20. Accordingly, the distance measuring device 20 can receive the distance measuring instruction sent by the processor 30, and can perform distance measuring according to the distance measuring instruction to obtain the distance to the distance measuring target object. The processor 30 and the distance measuring device 20 here respectively have corresponding communication modules to realize communication between the two.

[0034] The processor 30 is also connected in communication with the camera 10, and can determine the focus data according to the distance measurement data and send the focus data to the camera 10, and can receive the captured image sent by the camera 10. Accordingly, the camera 10 can receive the focus data sent by the processor 30, and can focus according to the focus data, and the camera uses the distance measurement target of the distance measurement device 20 as the image capture target and captures the image of the image capture target, and can send the captured image to the processor 30. The processor 30 and the camera 10 also have corresponding communication modules respectively to realize the communication connection between the two.

[0035] In some embodiments, after receiving the distance measurement instruction, the distance measurement device 20 performs distance measurement, and when the distance measurement device 20 performs distance measurement, it can send distance measurement data to the processor 30 at a preset frequency to increase the flexibility of distance measurement. In some embodiments, the preset frequency can be set within the range of 20Hz-100Hz. For example, it can be set to 50Hz. The preset frequency can be set in combination with the clock frequency in the mobile device, and can be set to a multiple of the clock frequency. This application does not limit this and can be set according to the specific application environment.

[0036] Please combine Figure 2 As shown, in some embodiments, the camera device 10 may specifically include a driver 11, a drive motor 12 and a camera lens 13. The camera device 10 is capable of receiving the focus data sent by the processor 30, and is capable of focusing according to the focus data. Specifically, it can be understood that the driver 11 is capable of receiving the focus data sent by the processor 30, and is capable of driving the drive motor 12 to work according to the focus data to adjust the position of the camera lens 13, such as moving in a direction close to the camera target, or moving in a direction away from the camera target, to achieve focusing. The driver 11 can specifically receive the focus data sent by the processor 30 through a corresponding communication module. Accordingly, after the camera lens 13 captures an image, it is first transmitted to the driver 11, and then the driver 11 sends the corresponding image to the device 30.

[0037] The focus data mentioned here may include the distance and the moving direction of the lens. The distance measurement data mentioned here may include the distance between the distance measurement device 20 and the distance measurement target object measured by the distance measurement device 20.

[0038] In some embodiments, the mobile device 100 may further include an image display device (not shown). The image display device may be used to display the imaged images captured by the camera device 10. The display device may be connected to the processor 30 for data exchange.

[0039] Based on the above structure, when the user uses the mobile device 100 to take photos and videos, if the image captured by the camera device 10 includes multiple objects or people at different distances from the mobile device 100, the user can pre-select one of the objects or people as the image capture target by touching the display device. Accordingly, the display device can send an instruction to select the image capture target to the processor 30. After the processor 30 receives the instruction to select the image capture target, it can generate a corresponding distance measurement instruction and send the corresponding distance measurement instruction to the distance measurement device 10, so that the distance measurement device 10 can measure the distance between it and the distance measurement target. Of course, in some other embodiments, for a single object or person in the image capture by the camera device 10, the processor can directly send a distance measurement instruction to the distance measurement device. In addition, for a mobile device 100 with a recommended target function, if the user has no doubts about the recommended image capture target, the processor can also directly send a corresponding distance measurement instruction according to the image capture target recommended by the mobile device 100 itself. For example, the processor may be set with a target selection time threshold. When the user previews the image captured by the camera device, if the recommended time for the camera target recommended by the mobile device 100 reaches the selected time threshold, and the processor still does not receive an instruction to select the camera target, the processor may automatically send a distance measurement instruction corresponding to the recommended camera target to the distance measurement device. This application does not limit this, and it can be set according to the specific application environment.

[0040] Usually, when the distance measurement target is consistent with the imaging target, the camera device focuses accurately, and the camera device can capture a clear image of the required imaging target. However, when the distance measurement target is inconsistent with the imaging target, the focusing result of the camera device according to the focusing data corresponding to the distance measurement data is not accurate enough, and the image of the imaging target captured by the camera device will be affected to a certain extent. After research, the inventors found that when there are many layers of objects or people around the imaging target, the distance measurement data obtained by the distance measurement device may be the distance measurement data between the distance measurement device and the objects or people around the imaging target. If the camera device focuses according to the distance measurement data, there will be problems of out-of-focus such as focus point offset and poor focusing effect, and the focusing speed is slow and the focusing efficiency is low. The mobile device 100 provided in the present application can solve this type of technical problem well.

[0041] In some embodiments, the distance measuring device 20 includes a time of flight (TOF) distance measuring device. The distance measuring device 20 uses a time of flight distance measuring device, which is conducive to quickly obtaining distance measurement data and improving the focusing efficiency of the camera device. The distance measuring device 20 can use infrared laser to measure distance. Specifically, the distance measuring device 20 may include a distance measuring transmitting end and a distance measuring receiving end. The distance measuring device 20 can use the time from the infrared laser being emitted from the distance measuring transmitting end to the distance measuring receiving end receiving the infrared laser, as well as the speed of the infrared laser to determine the distance between the distance measuring device 20 and the distance measuring target.

[0042] Please combine Figures 3 to 6 As shown, it can be understood that Figure 3 The up and down directions indicated in the figure are for the convenience of describing directions, and do not limit the directions of the camera device 10, the distance measuring device 20, and the entire mobile device 100. Figure 3 For example, the imaging target object can be understood as being located above the imaging device 10 and the distance measuring device 20 .

[0043] In the mobile device 100, at least part of the distance measuring surface of the distance measuring device 20 is located in the imaging surface of the camera device 10. In combination with FIG4, in the imaging reference plane, the field of view center of the camera device 10 is located in the distance measuring reference field of view of the distance measuring device 20. The distance measuring device 20 and the camera device 10 are arranged in this way, so that the distance measuring target of the distance measuring device 20 is consistent with the imaging target of the camera device 10, which is conducive to improving the accuracy of the focusing of the camera device and improving the shooting effect of the mobile device.

[0044] The camera reference plane mentioned here can be understood as the plane with a shooting distance equal to 150mm. Figure 3For example, it can be understood as a plane located above the camera device 10 and 150 mm away from the upper surface S101 of the camera device 10. The imaging plane is the area that the camera device 10 can capture on the camera reference plane. The ranging plane is the area that the ranging device 20 can detect on the camera reference plane. The ranging reference field of view is the area that the ranging device 20 can detect on the camera reference plane based on the ranging reference field of view angle. In the camera reference plane, the field of view center of the camera device 10 is the center of the imaging plane. It is the common center (center of the circle) of the ranging plane and the ranging reference field of view.

[0045] In some embodiments, the imaging surface may be a circular area. Figure 4 The imaging surface S1 shown in FIG. The area corresponding to the imaging surface S1 is a circular area. Figure 5 The imaging surface S1' is shown. Correspondingly, in the imaging reference plane, the field center O1' of the imaging device is the center of the imaging surface S1. In the imaging reference plane, the field center O1" of the imaging device is the center of the imaging surface S1'. Of course, the imaging surface can also be an area corresponding to a rectangle or other shapes. The specific shape of the imaging surface can be determined by the shape of the photosensitive array of the imaging device, etc., and this application does not limit this.

[0046] In some embodiments, the ranging surface may be a circular area. Figure 4 The distance measuring surface S2 shown. The area corresponding to the distance measuring surface S2 is a circular area. Of course, the distance measuring surface can also be an area corresponding to a rectangle or other shapes. For example Figure 5 The distance measuring surface S2' shown. The area corresponding to the distance measuring surface S2' is a rectangular area. The specific shape of the distance measuring surface can be determined by the arrangement shape of the light source array at the transmitting end of the distance measuring device and the receiving array at the receiving end, etc., and this application does not limit this. In some embodiments, the distance measuring reference field is a circular area. For example Figure 4 The ranging reference field S3 is shown, and Figure 5 The ranging reference viewing field S3' is shown. Accordingly, the ranging plane S2 and the ranging reference viewing field S3 have a common center O2'. The ranging plane S2' and the ranging reference viewing field S3' have a common center O2".

[0047] Further, the camera device 10 has a first calculated field of view angle θ1. In some embodiments, the first calculated field of view angle θ1 is the smallest of the optical horizontal field of view angle and the optical vertical field of view angle of the camera device 10, which facilitates the determination of the first calculated field of view angle and makes the determined first calculated field of view angle of the camera device 10 unique, which facilitates the calculation and determination of the relative position of the distance measuring device and the camera device. The optical horizontal field of view angle and the optical vertical field of view angle of the camera device 10 can be obtained from the lens parameters of the camera device or the specification of the lens.

[0048] Furthermore, the ranging device 20 has a second calculated field of view angle θ2. In some embodiments, the second calculated field of view angle θ2 is the smallest of the transmitting end field of view angle of the ranging transmitting end and the receiving end field of view angle of the ranging receiving end, which facilitates the determination of the second calculated field of view angle and makes the determined second calculated field of view angle of the same ranging device unique, which facilitates the calculation and determination of the relative position of the ranging device and the camera device. The transmitting end field of view angle of the ranging transmitting end and the receiving end field of view angle of the ranging receiving end can be obtained from the parameters or specifications of the ranging device. Accordingly, the above-mentioned ranging reference field of view angle can be 0.27*θ2, so that the field of view center of the camera device 10 is closer to the center of the ranging surface, which is conducive to making the ranging target of the ranging device 20 consistent with the camera target of the camera device 10.

[0049] Please combine Figure 3 and Figure 4 As shown, Figure 3 The upper surface S101 of the camera device 10 can be understood as the camera surface. The upper surface S201 of the distance measuring device 20 can be understood as the first surface facing the side of the camera target. O1 is the center point of the camera surface, and O2 is the center point of the first surface. R1 is the center line of the camera device 10 passing through O1. R2 is the center line of the distance measuring device 10 passing through O2. Δh is the vertical distance between the camera surface of the camera device 10 and the first surface of the distance measuring device 20. The vertical distance Δh can be obtained from the specification of the mobile device or the specification of the camera device 10 and the distance measuring device 20. The vertical distance can be a positive number, a negative number or zero, depending on the position between the camera surface and the first surface. d1 is the diameter of the lens corresponding to the first calculated field of view angle of the camera device 10, and d1 can be obtained from the parameters of the lens or the specification. d2 is the diameter of the distance measuring surface corresponding to the second calculated field of view angle of the distance measuring device 20, and d2 can be obtained from the relevant parameters or specifications of the distance measuring device. L is the vertical distance between the center of the imaging device 10 and the center of the distance measuring device 20 .

[0050] Correspondingly, combined with the above description, it can be calculated that:

[0051] The diameter D1 of the imaging surface S1 of the camera device 10 is expressed by the following formula (1):

[0052] D1=2*150*tanθ1+d1 (1);

[0053] The diameter D2 of the distance measuring surface S2 of the distance measuring device 20 is as follows:

[0054] D2=2*(150+Δh)*tanθ2+d2 (2);

[0055] In combination with the fact that at least part of the distance measuring surface S2 of the distance measuring device 20 is located within the imaging surface S1 of the camera device 10, the following formula (3) can be obtained:

[0056] D2 / 2+L <D1 / 2 (3);

[0057] Combined with the above, in the camera reference plane, the field of view center O1' of the camera device 10 is located in the distance measurement reference field of view S3 of the distance measurement device 20, and the following formula (4) can be obtained:

[0058] L / (D2 / 2) < (150+Δh)*tan(0.27*θ2)+d2 / 2 (4);

[0059] Substituting the above formulas (1) and (2) into formula (3), we can obtain the following formula (5):

[0060] L< 150*tanθ1-(150+Δh)*tanθ2+(d1-d2) / 2 (5);

[0061] Substituting the above formulas (1) and (2) into formula (4), we can obtain the following formula (6):

[0062] L< [(150+Δh)*tan(0.27*θ2)+d2 / 2]*[(150+Δh)*tanθ2+d2 / 2] (6);

[0063] Furthermore, by transforming the above formula (5) and formula (6), we can get:

[0064] L<{(150*tanθ1-(150+Δh)*tanθ2+(d1-d2) / 2}∩{[(150+Δh)*tan(0.27*θ2)+d2 / 2]*[(150+Δh)*tanθ2+d2 / 2]}.

[0065] That is, the vertical distance L between the center of the camera device 10 and the center of the distance measuring device 10 satisfies the condition:

[0066] L<{(150*tanθ1-(150+Δh)*tanθ2+(d1-d2) / 2}∩{[(150+Δh)*tan(0.27*θ2)+d2 / 2]*[(150+Δh)*tanθ2+d2 / 2]};

[0067] Among them, Δh is the vertical distance between the camera surface of the camera device and the first surface of the ranging device facing the side of the camera target, θ1 is the first calculated field of view angle, θ2 is the second calculated field of view angle, d1 is the diameter of the lens corresponding to the first calculated field of view angle θ1 of the camera device, and d2 is the diameter of the ranging surface corresponding to the second calculated field of view angle θ1 of the ranging device.

[0068] Please refer to Figure 3 and Figure 5 , and when necessary, combine Figure 4 As shown, Figure 5 Shown with Figure 4 The difference shown is that Figure 4 The distance measuring surface S2 shown is a circular area, and Figure 5 The distance measurement surface S2' shown is a rectangular area. Figure 5 The corresponding field of view angle corresponding to the short side of the ranging surface S2' of the ranging device can be understood as the second calculated field of view angle θ2. This field of view angle can correspond to the smallest one of the transmitting end field of view angle of the ranging transmitting end and the receiving end field of view angle of the ranging receiving end. Figure 5 In the embodiment shown, D2 is the distance between the two long sides of the distance measuring surface S2' (i.e., the length of the short side). It is understandable that if the imaging surface is rectangular, D1 can be the distance between the two long sides of the imaging surface (i.e., the length of the short side) when calculating.

[0069] Further, in some embodiments, the distance measurement receiving end may be located at the center of the side of the distance measurement device 20 facing the imaging target or at the center relatively close to the imaging target. Figure 3 The position O2 shown, or other positions where the center line R2 on the distance measuring device 20 passes through, is convenient for arranging the camera device 10 and the distance measuring device 20, and is conducive to arranging the camera device 10 and the distance measuring device 20 at corresponding positions according to the vertical distance between the center of the camera device 10 and the center of the distance measuring device 20 determined above. Accordingly, the vertical distance L between the center of the camera device 10 and the center of the distance measuring device 20 can be understood as the vertical distance between the center of the camera device 10 and the center of the distance measuring receiving end of the distance measuring device 20.

[0070] Further, in some embodiments, the cross section of the camera device 10 is circular, and the cross section of the distance measuring device 20 is circular. The camera device 10 and the distance measuring device 20 are arranged in a circular shape, so that the structures of the two are more regular and beautiful, and are convenient for design and assembly. The cross section of the camera device is circular, which can at least be understood as the cross section of the camera lens 13 of the camera device 10 is circular. The cross section of the camera device mentioned here can be understood as a cross section perpendicular to the center line R1. The cross section of the distance measuring device 20 mentioned here can be understood as a cross section perpendicular to the center line R2.

[0071] In other embodiments, the cross section of the camera device 10 is rectangular. The cross section of the distance measuring device 20 is rectangular. The camera device 10 and the distance measuring device 20 with rectangular configuration have a more regular structure. The long side of the cross section of the camera device 10 is parallel to the long side of the cross section of the distance measuring device 20, and the short side of the cross section of the camera device 10 is parallel to the short side of the cross section of the distance measuring device 20, so that the arrangement of the two is more neat and beautiful. Figure 6 As shown, Figure 6 Shown is Figure 3 The side view of the camera device 10 and the distance measuring device from above can also be understood as a side view of the camera target object. Specifically, it can be understood that the long side 1011 of the camera device 10 is parallel to the long side 2011 of the distance measuring device 20. The short side 1012 of the camera device 10 is parallel to the short side 2013 of the distance measuring device 20.

[0072] Figure 7 2 is a block diagram of a mobile device according to an exemplary embodiment. For example, the device 2000 may be a mobile phone, a camera, a tablet computer, a wearable terminal device, etc.

[0073] Reference Figure 7 , the device 2000 may include one or more of the following components: a processing component 2002 , a memory 2004 , a power component 2006 , a multimedia component 2008 , an audio component 2010 , an input / output (I / O) interface 2012 , a sensor component 2014 , and a communication component 2016 .

[0074] The processing component 2002 generally controls the overall operation of the device 2000, such as operations associated with display, phone calls, data communications, camera operations, and recording operations. The processing component 2002 may include one or more processors 2020 to execute instructions to complete all or part of the steps of the associated method. In addition, the processing component 2002 may include one or more modules to facilitate interaction between the processing component 2002 and other components. For example, the processing component 2002 may include a multimedia module to facilitate interaction between the multimedia component 2008 and the processing component 2002.

[0075] The memory 2004 is configured to store various types of data to support operations on the device 2000.
